Similarly, as shown in FIG. 18, a cam surface 19b is formed on the bracket 18 at a position corresponding to a stopper device 64 described later. As a result, the ammunition 80 supported on the bullet sending tray device 28 only within a predetermined range during transportation.
It is possible to regulate the axial position of the. On the lower end side of the tray drive shaft 20 rotatably supported by the bracket 18, the above-mentioned bullet feed tray device 28, which is bent 90 degrees into an "L" shape, is attached, and the upper end side. The tray drive device 30 described above is connected to. As a result, as shown in FIG. 2, the ammunition 80 is delivered from the ammunition supply device (not shown) to the ammunition tray device 28 at the ammunition receiving position facing the ear shaft 14, and swung 90 degrees from this position. A bullet tray device 2 at the ammunition delivery position
It is designed to be delivered from 8 to the play bottom 32.

(Ship Feed Tray Device) As shown in FIGS. 3 and 4, the tray drive shaft 20 has a tray body 34 fixed to the lower end thereof. The tray drive shaft 20 is arranged so that its axis passes through the intersection of the gun axis G and the ear axis T. The tray main body 34 has a rectangular plate-shaped bullet-holding portion 34a and a bullet-shaped bullet-holding portion 34b having a similar shape which is orthogonal to the tray-like main body 34, and is bent in an "L" shape as a whole. It is joined to the tray drive shaft 20 so that. Four side holding plates 36 are arranged on the side portions of the bullet holding portions 34a and 34b for each bullet holding portion. The upper side of the side part holding plate 36 is rotatably supported by the tray main body 34 with a pin 78. The lower ends of the two side holding plates 36 on the same side surface are connected to both ends of the link plate 38 by pins 76, respectively. That is, four side holding plates 36, four pins 76, four pins 78, and two link plates 38 are provided on both sides of each bullet holding part.
Is provided. Thereby, the side part holding plate 36 can support the cylindrical part of the ammunition 80 from the side surface. Tray body 3
An ammunition guide plate 40 in the shape of a semicircular plate is arranged below 4. The ammunition guide plate 40 is a bracket for the breech device 12.
It is fixed to the hood 18 . This makes ammunition guide plate 4
0 can be lifted together with the barrel 10. As shown in FIG. 11, the ammunition guide plate 40 includes a notch-shaped guide portion 40.
a is formed. The width dimension of the guide portion 40a in the left-right direction in FIG. 11 corresponds to the width dimension of the play bottom 32 described later. Note that FIG. 11 shows a state in which the two lower holding plates 42 face each other and are fitted into the guide portion 40a. As shown in FIG. 4, the lower holding plate 4
A total of four 2 are provided, and each is rotatably supported on the upper surface side of the ammunition guide plate 40 by a pin 74. In the ammunition guide plate 40, the lower holding plate 42 mounting portion and the rotating portion thereof are lower than other portions,
Further, the upper surface of the lower holding plate 42 is arranged so as to match the upper surface of the ammunition guide plate 40. As a result, the breech bolt 32 can receive the ammunition 80 supported by the lower holding plate 42. The lower holding plate 42 is maintained in the position shown in FIG. 4 by respective spring mechanisms (not shown) when an external force in the rotating direction is not applied. That is, the lower holding plate 42 has the ammunition 80 in the state shown in FIG.
Are supported from below, the ammunition 80 is handed over to the breech bolt 32 while being pushed by the breech bolt 32 as it moves forward from the standby position and the tip ends thereof open sideways. This prevents the play bottom 32 from moving between the standby position and the loading position in front of it. As shown in FIG. 15, the empty drug discharge position is set at a swing position intermediate between the ammunition receiving position and the ammunition delivering position of the tray body 34. As shown in FIG. 16, the ammunition guide plate 40 has a discharge hole 40b formed at a position corresponding to the empty drug discharge position. The discharge hole 40b is provided at an intermediate position between the ammunition receiving position and the ammunition delivering position. The ammunition guide plate 40 is provided with a lid member 68 rotatably with a shaft 69. As a result, the lid member 68 can move between the illustrated hole opening position where the discharge hole 40b is opened and the hole closing position where the discharge hole 40b is closed. The lid member 68 is forcibly positioned at the hole opening position by a spring mechanism (not shown) when an external force is not applied to the lid member 68. As a result, when the tray body 34 holds the ammunition 80 and moves from the ammunition receiving position side to the ammunition delivery position side,
The side holding plate 36 and the ammunition 80 push the lid member 68 to the hole closing position against the spring force, so that the ammunition 80 is discharged into the discharge hole 40.
It is designed to be transferred without falling from b.
Further, when the tray body 34 holds the empty cartridge 82 and moves from the ammunition delivery position side to the ammunition receiving position side, the empty cartridge 82 can be discharged from the discharge hole 40b. In FIG. 11, a hollow tray drive shaft 20 is rotatably supported by a bracket 18 with a bearing 60. At the center of the tray drive shaft 20,
A torsion bar 62 is arranged. As shown in FIG. 12, the upper end portion of the torsion bar 62 is spline-connected to the bracket 18, and the lower end portion is spline-connected to the tray drive shaft 20. Torsion bar 62
Is attached so that the amount of twist is 0 (that is, the spring force is 0) when the tray body 34 is located at an intermediate position between the ammunition receiving position and the ammunition delivering position. Therefore, the torsion bar 62 exerts a force to swing the tray body 34 in the opposite direction regardless of whether the tray body 34 is at the ammunition receiving position or the ammunition delivering position. As a result, the driving force of the tray driving device 30 described later is small. The tray body 34, the side holding plate 36, the link plate 38, the ammunition guide plate 40, the lower holding plate 42, etc.
Is configured. In FIG. 1, the sending tray device 28
Receives the ammunition 80 from an unillustrated ammunition supply device at one of the two ammunition receiving positions (see FIG. 6), and is driven by the tray drive device 30 to receive the ammunition 80 while supporting the ammunition 80. It is designed to be moved to the ammunition delivery position which is swung 90 degrees from the position. At this time, the ammunition 80 delivered from, for example, the bullet holding portion 34b from the bullet feeding port of the bullet feeding device is pinched from both sides by a total of four side holding plates 36, and a stopper device 64 described later.
While being sandwiched from the front and rear by 66 and 66, the ammunition guide plate 40 is rolled and moved to the ammunition transfer position facing the playground 32. In this state, when the play bottom 32 advances from the position shown in FIG. 3 to the left loading position, the side part holding plate 36 and the link plate 38 are pushed upward and upward.
As a result, the side part holding plate 36 and the link plate 38 are set to
It does not interfere with the forward movement (loading operation) of.
As shown in FIGS. 13 and 14, the bullet-holding portions 34a and 34b of the tray body 34 have front stoppers 64 and rear portions at positions corresponding to the front end portion 80a and the rear end portion 80b of the ammunition 80, respectively. A stopper device 66 is attached. Since the stopper device 64 has the same structure as the stopper device 66, only the stopper device 66 will be described, and the description of the stopper device 64 will be omitted. As shown in FIG.
A plunger 71 is fitted in the case 70 so as to be movable in the axial direction. Plunger 71 in case 70
Spring 7 that exerts a force to push the smaller diameter side of the
2 are installed. Case 70, plunger 7
The stopper device 66 is constituted by 1 and the spring 72. The plunger 71 of the stopper device 66 is pressed against the cam surface 19a of the bracket 18, and as shown in FIG.
Are pressed against the cam surface 19b of the bracket 18. The cam surfaces 19a and 19b are arranged such that, in the ammunition receiving position, the plunger 71 of the stopper device 66 is located in the shortened position for releasing the ammunition 80, and the stopper device 6 is provided.
So that the plunger 71 of No. 4 is located at the extended position for supporting the ammunition 80, and further, the plunger 71 is located at the extended position for supporting the ammunition 80 while swinging between the ammunition receiving position and the ammunition delivering position. In addition, in the ammunition delivery position, the cam surface shapes of these stoppers 66 and 64 are set so that the plungers 71 of the stopper devices 66 and 64 are located in the shortened positions for releasing the ammunition 80, respectively. As a result, at the ammunition receiving position and the ammunition delivering position, the ammunition 80
Of the ammunition 80 can be transferred, and the axial position of the ammunition 80 can be regulated during the transportation.

(Tray Drive Device) In FIG. 8, a gear 26 is fixed to the upper end of the tray drive shaft 20.
Sector gears 48 and 50 are arranged so that they can be engaged with the gear 26 with the gear 26 interposed therebetween. Note that FIG. 8 shows a state in which the sector gear 48 is engaged with the gear 26 and the sector gear 50 is not engaged with the gear 26. The sector gears 48 and 50 are formed in a substantially fan shape as shown in FIG. A gear 52 is fixed to the shaft 22 of the sector gear 48. The shaft 22 is connected to the motor 46. The motor 46 is attached to a mounting portion (not shown) of the turret device 12. A gear 54 is fixed to the shaft 24 of the sector gear 50. The gear 54 is meshed with the gear 52. As a result, the motor 46
Drive the gear 52 and the sector gear 48 integrated with it.
Rotates in one direction, and the gear 54 and the sector gear 50 integrated therewith rotate in the opposite direction. As shown in FIG. 9, each of the sector gear 48 and the sector gear 50 has a shape that meshes with the gear 20 by a rotation angle of 90 degrees during one rotation. Further, the sector gear 48 and the sector gear 50 are arranged so as to mesh with the gear 26 in a state of being shifted from each other by 180 degrees. As a result, the gear 20 meshes only with the sector gear 48 for the first 90 degrees, for example, and does not mesh with any of the second 90 degrees,
Subsequently, a cycle is repeated in which 90 degrees are engaged only with the sector gear 50, and none of the last 90 degrees is engaged. That is, the tray drive shaft 20 integrated with the gear 26 rotates 90 degrees in the forward direction and stops for a predetermined time, and then rotates 90 degrees in the reverse direction and stops for a predetermined time. I will repeat. The sector gear 48 is provided with two partial cam-shaped cams 48a as shown in the figure at two positions on the upper surface thereof. Cam 48
With a, the lock 56, which will be described later, is brought into one of a locked state and an unlocked state as the sector gear 48 rotates. As shown in FIG. 10, a small diameter portion is formed on the gear 26, and two recesses 26a and 26b are formed on the outer peripheral side of the small diameter portion at positions 90 degrees apart from each other. A lock 56 is arranged at a position corresponding to the small diameter portion of the gear 26. The lock 56 is fitted to the support member 57 so as to be movable in the axial direction. The support member 57 is fixed to the bracket 18. A cam follower portion 56a protruding downward is formed at the right end portion of the lock 56 in the figure. That is, the lock 56 can be engaged with the cam 48a of the sector gear 48 by the cam follower portion 56a. A spring 58 is arranged in the support member 57. Spring 58
Applies a force to push the lock 56 toward the small diameter portion of the gear 26. As a result, when the cam 48a of the sector gear 48 engages with the lock 56 in response to the rotation of the sector gear 48, the lock 56 resists the force of the spring 58 and the gear 2 moves.
6 can be disengaged from the recess 26a (or the recess 26b), and when the cam 48a is disengaged from the lock 56, the lock 56 is moved to the recess 26a (or the recess 26b) of the gear 26 by the force of the spring 58. It is possible to fit. That is, when the gear 26 is not engaged with any of the sector gears 48 and 50, the gear 26 can be locked so as not to rotate due to vibration or the like. Sector gear 48, 5
0, the shafts 22, 24, the gears 52, 54, the motor 46, the lock 56, and the like constitute the tray drive device 30.

(Playing bottom and playing bottom drive device) The playing bottom 32 and the playing bottom drive device 44 are devices (loading devices) different from the ammunition supply device of the present invention, but they are related to each other in operation. I will explain. As shown in FIG. 4, the play bottom 32 is located behind the bullet holding portion 34a of the tray body 34 located at the ammunition delivery position. The play bottom 32 is the play bottom drive device 4
By being driven by 4 (see FIG. 1), it is possible to move between the standby position shown in FIG. 4 and the loading position shown in FIG. That is, the breech bolt 32 moves forward from the standby position to receive the ammunition 80 from the ammunition transfer tray device 28 located at the ammunition delivery position, and further advances to reach the loading position to load the ammunition 80 on the barrel 10. Also, after firing, while moving backward from the loading position to receive the empty cartridge 82 from the barrel 10,
After further retracting and delivering the empty cartridge 82 to the bullet sending tray device 28, the standby position is reached.

Next, the operation of this embodiment will be described. Figure 2
As shown in FIG. 5, the bullet holding part 34a of the bullet feed tray device 28 holds the ammunition 80 and is positioned at the ammunition transfer position, and accordingly, the bullet holding part 34b remains empty and the left side surface as seen from the breech. It is assumed that it is located at the side ammunition receiving position and the playground 32 is located at the standby position. In this state, the stopper device 66 on the rear side allows the ammunition 80 to move in the axial direction as shown in FIG. 17A, and the stopper device 6 on the front side.
4 also allows the ammunition 80 to move in the axial direction as shown in FIG. When the breech bolt drive device 44 operates, the breech bolt 32 moves forward and the lower holding plate 42 and the side holding plates 36 are moved.
While pushing away, the ammunition 80 is received from the bullet holding part 34a, further advances to reach the loading position, and the ammunition 80 is loaded on the barrel 10. At this time, the play bottom 32 hits the front shock absorber 84 before reaching the loading position, and is stopped at the loading position while the forward speed is reduced. Although the breech bolt 32 is stopped at the loading position until the end of firing, a force in the backward direction is exerted by the front shock absorber 84, so that the driving force of the breech bolt drive unit 44 can be small. After the firing, the breech bolt 32 retracts to pull out the empty cartridge 82 left in the barrel 10, and further retracts to deliver the empty cartridge 82 to the bullet holding part 34a to return to the standby position again. In this case as well, the play bottom 32 reaches the standby position before
The vehicle hits the rear shock absorber 86 and is stopped at the standby position while the reverse speed is being reduced. Although the breech bolt 32 is stopped at the loading position until the end of the firing, a force in the forward direction is applied by the rear shock absorber 86, so that the driving force of the breech bolt drive unit 44 can be small. During this time, the ammunition 80 is sent from the bullet supplying device (not shown) to the bullet holding portion 34b. At this time, the stopper device 66 on the rear side allows the ammunition 80 to move in the axial direction as shown in FIG. 17 (c1), but the stopper device 64 on the front side does not move as shown in FIG. 18 (c1). The axial movement of the ammunition 80 is restrained. As a result, the ammunition 80 can be sent to a predetermined position of the bullet holding portion 34b. Next, the tray drive device 30 is operated, so that the feed tray device 28 is swung counterclockwise in FIG. Since a counterclockwise force is applied to the tray drive shaft 20 by the torsion bar 62 at the start of this swinging, the starting force of the tray drive device 30 is small. During swinging, the stopper device 66 on the rear side is
As shown in FIG. 17 (b2), the axial movement of the ammunition 80 is restrained, and the stopper device 64 on the front side also restrains the axial movement of the ammunition 80, though not shown. There is. When the tray body 34 swings about 45 degrees, the empty shell 82 is discharged from the discharge hole 40b of the ammunition guide plate 40, and the bullet holding portion 34a is emptied. At this time, the ammunition 80 held in the bullet holding portion 34b closes the discharge hole 40b on the opposite side by pushing the lid member 68 in the closing direction, so that the ammunition 80 is conveyed without falling from the discharge hole 40b. When the tray main body 34 swings 90 degrees, the bullet holding portion 34a
Is located at the ammo receiving position on the right side when viewed from the breech, and the bullet holding portion 34b is correspondingly located at the ammunition delivery position. After the operations of loading ammunition 80, firing ammunition 82, removing ammunition 80, and feeding ammunition 80 into bullet holding portion 34a are performed in the same manner as described above, the ammunition tray device 28 is moved to FIG.
After being swung in the clockwise direction and the empty cartridge 82 is discharged from the discharge hole 40b on the opposite side of the ammunition guide plate 40, the initial state is restored. Even when the feed tray device 28 is swung in the clockwise direction, a force in the clockwise direction acts on the tray drive shaft 20 by the torsion bar 62 at the start of the swing, so the starting force of the tray drive device 30. Is designed to be small. By repeating such a cycle, ammunition 80
It is also possible to discharge the empty cartridge 82 from the gun.

[0011]

As described above, according to the present invention,
Ammunition has its axis between the ammo receiving position and the ammunition delivering position
Is oscillated in a partial arc so that the direction of
Even if it is of a type that does not use a bullet feed device with a large moving space such as a flexible chute,
A small ammunition supply device can supply ammunition to the gun . Also, place the empty cartridge after launch in the ammunition supply device.
Since it can be discharged to the outside by a simple discharge mechanism, it is not necessary to use a device dedicated to emptying
Yes. Therefore, the device can be made small and inexpensive.
